I have a temperature lookup table in the 11th and 12th blocks, and when I erase block 9, I no longer have a termperature when I run my program on the microcontroller. It is definitely erasing those blocks. When I looked at it with the display flash memory function in FM, those blocks show all FFs, when before they had floating point numbers.

I did all of those steps. I am familiar with the change from the old RD2Hxx chip to the plain RD2xx chip, and that is what I selected. The list of blocks is correct, but for some reason, erasing that 9th block also erases 10,11 and 12. Had not noticed this before because my code used to fit in the first 8 blocks, and only recently grew to use the 9th block. Also just updated the program on the computer I use to program the chips last week from a 2.40 version of Flash Magic.

I have been using Flash Magic for years, and before that WinISP. I just downloaded the latest version of FlashMagic and appear to be having a problem with the erase feature on it for the P89C51RD2 chip. When I try to erase blocks 0-8 of the chip, either manually or using the erase blocks used by hex file (0x0000 to 0x8FFF), instead of erasing just those files, it also erases blocks 9, 10, 11 and 12, which is where my lookup tables, etc. are and I do not want erased. What is going on? Any ideas?

Update, I tried back as far as 3.22 on Flash Magic and it does the same thing. I think it is just when you try to erase block 8, it erases the whole 16 kB block like it thinks it is an old RD2HA chip.
